To all whom it may concern: 7

Be it known that I, ALEXANDER E. Knrrrr, a citizen of the United States of America, and resident of Hinsdale, Dupage county, Illinois, have invented, a certain new and useful Improvement in Gas-Compressing or Gas-Circulating Systems and Apparatusfor V gine;

My invention also relates to special" valve for use in the system when the pressure is obtained by combustion.

Among the objects of my invention are.

the following: to provide a valve for an air.-

compressing or circulating system, which prevents leakage by maintaining the valve below a non-gaseous fluid; to provlde a gascompressing or circulating system in which 7 the gas may be generated and compressed by the combustion of any suitable material; to

provide an improved valve for use in a sys-. tem of the above "character in which the pressure is produced by combustion ;'to provide means between the combustion chamber and the valve for protecting the valve; and to provide certain details'and features of improvement tending to increase the efiiciency and serviceability of a gas-compress ing or circulating system and apparatus applicable for use therewith.

' To the foregoing and other useful ends my invention consists in matters hereinafter set forth andclaimed.

In the accompanying drawings Figure 1 represents agas-compressmg or circulating system and shows the point at wh1ch the improved valve may be inserted. Fig. 2 shows a section ofsaid valve. Figs. 3 and 4 show screens that may be used for protecting. the valve. 7 V x In the drawings like characters refer to like parts. i I

Referring to Fig. 2 the cylinder-A con sists of a cup B, a cap C, and the terminal D. IVithin the cylinder there is a valve E provided with a pin FQ Over the valve there is a perforated screen G. This screen is held in place by a sprlng H, which latter Specification of Letters Patent. Pgt itl df ,15,1915;

is made tall enough to-rise above. the 'surfaceof the liquid, asindicated. The valve may be placed in' the i line atany point be-' tween the ooi'nt'of compression N'and the reservoir 0. (See Fig. 1).;The endD of the cylinder A is connectedto'the intake line and the pipe K is connectedto the reservoir. When the pressure in" the intake pipe be comes suiiiciently hi ghto raise the valve E, the gas passes first directly into" the portion of the liquid within the screen .G and then through the aperturesfof the screen into the upper part of the chamber. .The object in providing thefscreen is to'check the violent action of .the liquid due to the passage of air, and prevent the liquid being carried up to and through the. pipe K. This action maybe further .controlleclby the valve L, bv

means of which. latter the size of the outlet is regulated; By making the outlet small the pressure in the upper part 'ofthe, chamber A is increased and thejstream If desired, the springs'H and I may be provided with any suitable tension regula;

Pa s e .mto pipe K becomes more constant. I

tors. 1 When the valve is used in connection f V with an internal combustion engine or other. similargas'and pressure generator, there 1s provided in the intake line a fire and heat 7 screen, such as shown in the termlnalD,

This, screen may be" made up offone or more i perforated disks or plates M. '(See Figs. 3 and 4.) These plates maybe made to any suitable'thickness and perforated in any sultable manner. If, desired, the screen may be made of a single plate and I dontglimit myself to any particular character of screen. Vsith theconstruction described a gas pipe"; valve may be'obtained. This valve may be placed in the intake line at any point and the screen may-be placed at any, point'between the pressure generator'and'the valve. I

What I claim as my invention is 1. The-combination of-a valve and a non;

gaseous fluid for covering the valve and a porous screen on the intake side of the valve and one on the outlet side. 7

2. The combination of a valve, a screen over the valve and over a volume of a nongaseous fluid, the latter being sustained by, the valve, a'source of .gas'supply connected to the valve for operating the valve and for blowing the fluid away from the valveopeningwhile the gas is passing, saidscrecn operating to restrict the ebullition of the fluid. r v 1 3. The combination of a volume of a non-- gaseous'fiuid, a valve beneath the fluid, a source of gas supply connected to the valve, a gas chamber over the fluid for receiving thegas after it passes through the valve and fluid, an outlet from said chamber restricted in size to prevent a too rapid exit of the gas from the chamber, and to prevent also the fluid being carried over with the gas.

4. The combination of a combustion chamber for supplying, gas under pressure, .a valve, a pipe line connected to the chamber and the valve, and a heat screen between the chamber and the valve. a

5. The combination of a combustion chamber for supplying gas under pressure, a valve, a pipe line connected to the chamber and the valve, and a perforated plate acting as a heat screen between the chamber and the valve.

(3. The combination of a combustion chamber for supplying. gas under pressure, a valve, a pipe line'connected to the. chamber and the valve,and a perforated plate serving as a the screen between the chamber and the V valve. v

7 The combination of a combustion chamber for supplying gas under "pressure, a valve, a volume of non-gaseous fluid resting over said valve, a-Vpipe line connected. to the chamber and the valve, and a heat screen between the chamber and the valve. I 8.5The combination of a volume of a non gaseous fluid, a valve-beneath the fluid sustaining the latter, a source of gas supply connected to the valve for operating the latter and preventing the fluid from passing toward the source of gas, said source ofigas Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents;

being supplied. by combustion of suitable material, and a heat and tire screen interposed between the. source of gas supply and the valve. I

9. The combination of a valve, a screen;

over the valve and over a volume of a non gaseous fluid, the latter being sustained by the valve a source of as su vol connected to the valve for operating the valve and for blowing the fluid away from the valve-open ing while the gas is passing,;said screen operating to; restrict theebullition of theifiuid, said source of gas being supplied by combustion of suitable material, and a heat and fire screen interposed between the sourceof' gas supply and thevalve, l0. The combination of a volume of a non gaseous fluid, a valve beneath the fluid, a

sourceof gas supply connected to the valve,

a gas chamber over the fluid for receiving source of gas being supplied by combustion of a suitable material, and a heat and fire screen interposed between the sourceof gas supply and the valve.

11. The combination of a valve, a chamber containing the valve, a non-gaseous fluid resting on the valve, and ascreen over the valve. 7 g I 12.. The combinatlon of a valve, a chamber containing the valve, a 110ng2tS6011S ,fi11lCl perforated screen I resting on the valve, anda over the valve.
